Abstract

Phase pure (Ba_0.3Sr_0.7)(Zn_1/3Nb_2/3)O₃ (BSZN) perovskite ceramic nanocrystalline particles were synthesized at low temperature with high reaction yield and high synthetic reproducibility using the sol–gel technique. The results showed that high-purity perovskite BSZN phase with high crystalline quality was obtained at 800 °C, that is, the volatilization of ZnO was successfully overcome. The nanocrystalline particles were about 20–30 nm in diameter with regular and uniform spherical shapes, high dispersive properties, and less aggregation. The pellets made by these nanoparticles had excellent dielectric properties: dielectric constant \( \varepsilon_{\text{r}} \) 40.5, temperature coefficient of resonant frequency \( \tau_{\text{f}} \) 0.5 × 10⁻⁶/ °C, and quality factor Q × f: 75,000 at 3.89 GHz, and a high relative density of 98.1 %.
